Column properties
By specifying column properties, you can determine which column data types are to be processed instead of using the default data types that are applied by the algorithms. You can determine also the column role that a column has in the computation that is done by the algorithm.
Each algorithm uses specific column roles. Column types have a defined set of values.
You can specify column properties in parameters or in a column properties table. To identify nominal columns and numeric columns, you can use property values.
The following column types are valid:
- nominal [nom]
- continuous [cont]
